NZS/AS 1319:1994 advocates simplicity and clarity in safety signage. To be effective, they should be easy to read and interpret at a glance.

The Standard is about the use of legible text and appropriate, simple symbols.

By simplifying the message, it reduces the risk of misinterpretation, which increases the chances of the sign’s warning or instruction being followed.
